Watermark Detector Based on Stochastic Resonance Phenomenon
(2013-02)
In this work it is presented an application of the
striking
Stochastic
Resonance
phenomenon
to
Telecommunication field. This allows the detection of signals in
very low signal-noise scenarios only if the appropriated ...
Stochastic resonance in a nonlinear mechanical vibration isolation system
(2016-05-26)
This paper concerns the effect that a stochastic resonance can have on a vibration isolation system. Rather than reducing the transmitted force, it is shown that it is possible to significantly mask the component of the ...
Stochastic resonance in a linear system: An exact solution
(2006)
Multistable systems can exhibit stochastic resonance which is characterized by the amplification of small
periodic signals by additive noise. Here we consider a nonmultistable linear system with a multiplicative noise
forced ...
Weak signal enhancement by nonlinear resonance control in a forced nano-electromechanical resonator
(Nature, 2020)
Driven non-linear resonators can display sharp resonances or even multistable behaviours amenable to induce strong enhancements of weak signals. Such enhancements can make use of the phenomenon of vibrational resonance, ...
Ghost stochastic resonance induced by a power-law distributed noise in the FitzHugh?Nagumo neuron model
(Elsevier Science, 2015-05)
We numerically investigate the ghost stochastic resonance phenomenon induced by a power-law distributed noise in the neuron FitzHugh–Nagumo model. The input noise considered is produced by a Langevin process including both ...
Subharmonic stochastic synchronization and resonance in a neuronal system
(American Physical Society, 2002-10)
We study the response of a model neuron, driven simultaneously by noise and at least two weak periodic signals. We focus on signals with frequencies components kf0,(k+1)f0,…(k+n)f0 with k>1. The neuron’s output is a sequence ...
The ghost of stochastic resonance: an introductory review
(Taylor & Francis Ltd, 2012-01)
Nonlinear systems driven by noise and periodic forces with more than one frequency exhibit the phenomenon of Ghost Stochastic Resonance (GSR) found in a wide and disparate variety of fields ranging from biology to geophysics. ...

Effects of noise on the internal resonance of a nonlinear oscillator
(Nature Publishing Group, 2018-12)
We numerically analyze the response to noise of a system formed by two coupled mechanical oscillators, one of them having Duffing and van der Pol nonlinearities, and being excited by a self-sustaining force proportional ...
